I've been taking care of dogs of my own for all my life. I've been house sitting and watching neighbors dogs for just as long. I can handle large and agressive dogs as long as I'm forewarned. I generally won't report biting unless it requires a hospital visit. I've worked with tiny dogs and large dogs. Im certainly willing to take special request in order to make the owner more comfortable. A huge part of dog sitting and walking is trust between the owner and the dog walker. I hope to build a healthy trust between myself and my clients. Feel free to text or call me if you need any more info.( texting will generally work better) I look forward to meeting your dog. limited time offer: get a free walk with the purchase of any other service.
